PAFER-MAKING MECHANISM.

Application filed. August 26, 1926. Serial No. 181,775.

providing an. adjustable apron on the wire of the paper machine adapted to. move with the wire bodily as the wire is vibrated.

I have found that, by'adjusting this apron and moving it with the wire, I am enabled to prevent ripples and to use the same machine for making different kinds and weights of paper. I

Referring to the drawings:

Figure 1 is a side elevation of one end of the paper machine with my invention applied thereto;

Figure 2 is a diagrammatic view of one 20 form of my invention and its application to a paper machine;

Figure 3 is an end elevation of the machine partially broken away to show the method of mounting the apron support on 25 the machine to move transversely with it;

Figure 4 is a detail side elevation of the vibrating mechanism for the wire and wire support, together with the support for the apnon and the apron; Figure 5 is a detail elevation of the adjusting means for the apron roller.

Referring to the drawings in detail, 1 is a 7 flow box containing stock, which stock flows on to ,a stock table 2 between the boards 3 until it comes in contact with the slice 4 adjusted by the screw 5. The stock passes beneath the slides" in the usual manner on to thepaper-making wire screen 6. 7' is the usual deckle strap passing over the Wheel 8 carried on the frame 9. 9 designates a frame mounted on the foundation 10.

This foundation carries a plurality of spring members 11. adapted to reciprocate at their free ends which are connected to the supports 12 of the machine. This support 12 carries on a bracket 13 the shaft 14: which supports the rubber apron constituting a part of my invention.

This apron 15 may be adjusted as to the amount of it whichis unwound by the handle 16 on the shaft 14, the ratchet 17 and the pawl 18.

I have found that the lighter the paper to be made, the further the apron should extend along the wire.

I have also found that my apron catches the stock and insures its delivery and dis- 1 tribution upon the wire in such away that the stock vibrates but does not stand on end. To thecontrary, the films lay smoothly and evenly preventing the formation of streaks in the paper.

By moving my apron with the wire, I prevent any relative movement between the two, which would upset the vibration and disarrange the films, resulting in apoor quality of paper.

In order to impart a vibratory movement of the wire and apron and the breast roll 19 on which the wire is mounted andover which. it passes, I provide an eccentric generally designated 20 operating a pitman 21,

a slide 22 in a guide 23 and the upper free ends of the spring 11.

This spring is connected to the frame 12 which causes the breast roll 19 and the shaft 14: of the apron to travel together in a transverse vibratory movement of the machine.

The machine shown isthe conventional type of machine, and it will be realized that my invention is adaptable to any type or design of machine.

It will be noted that the shaft 14 is supported at either end in a block 24 which fits in a rectangular cutaway space 25 in the bracket 13. This block is positioned in the cutaway space 25 in the bracket 13. This block is positioned in the cutaway space 25 by the set screw 26, thereby enabling an adjustment of the position of the apron and particularly its outer free edge relative to the wire.

I desire to comprehend within my invention such modifications as may be necessary to adapt it to var ing conditions and uses.

. Having thus ully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In combination in a paper machine of a paper-making wire, means to supply stock thereto, and an apron, and means tomove said apron and wire together.

2. In combination in a. paper machine of a vibrating, paper-making screen and an adjustable apron adapted to vibrate therewith.

3. In combination in a paper machine, a vibrating pervious paper-making means, a vibrating impervious apron, said apron and paper means being adapted to vibrate together in unison.

t. In combination in a paper machine, a

vibrating pervious paper-making means, a vibrating impervious apron, said apron and paper means being adapted to vibrate together in unison, and mean to deliver stock on to said apron when said stock flows on to said paper-making means, and means for regulating the amount of stock so delivered.

5. In a method otmaking paper without streaks, vibrating a paper screen, vibrating an apron therewith and delivering the stock on to the apron and thence on to the screen.

(5. In a method of making paper without streaks, vibrating a paper screen, vibrating an apron therewith and delivering the stock on to the apron and thence on to the screen, and adjusting the amount of the apron lying on the screen according to the weight of the paper to be made.

7. In combination in a paper making machine of a breast roll, a wire screen passing thereover, a frame adapted to vibrate said screen, brackets mounted thereon for supporting an apron roller, an apron roller,

re ireae means to maintain said apron roller in varying positions, means to move said apron roller, an apron thereon and means to deliver stock and control the amount so delivered on to said apron and thence on to said screen whereby said apron and said screen will vibrate together in unison.

8. In combination in. a paper machine of a paper-making wire, an apron, means to support said apron whereby it Will move with said wire, means to vibrate said Wire and apron, and means to adjust the relative position of said apron to said Wire, and means to adjust the length of said apron.

9. In combination in a paper making machine ot' a wire anda breast roll, means to support and to move therewith an apron roller, an apron, means to adjust the position of said apron roller at either end in its support and means to adjust the length of said apron on the wire.

In testimony whereof I aflix my signature.
